2'-Methyl-2'-nitro-1'-phenyl-2',3',5',6',7',7a'-hexa-hydro-spiro-[indoline-3,3'-1'H-pyrrolizin]-2-one.

ABSTRACT: The title compound, C(21)H(21)N(3)O(3), was synthesized by a multi-component 1,3-dipolar cyclo-addition of azomethine ylide, derived from isatin and proline by a deca-rboxylative route, and (E)-1-phenyl-2-nitro-propene. In the mol-ecule, the spiro junction links a planar oxindole ring and a pyrrolidine ring in an envelope conformation. The mol-ecular packing is stabilized by an inter-molecular N-H?N inter-action of the oxindole and pyrrolizidine rings.

Crystal structure of 2'-[(2',4'-di-fluoro-biphenyl-4-yl)carbon-yl]-1'-phenyl-1',2',5',6',7',7a'-hexa-hydro-spiro-[indole-3,3'-pyrrolizin]-2(1H)-one.

Project description:In the title pyrrolizidine derivative, C33H26F2N2O2, both pyrrolidine rings of the pyrrolizidine moiety adopt an envelope conformation. The di-fluoro-phenyl group is oriented at an angle of 54.3?(1)° with respect to the oxindole moiety. The crystal packing features an N-H?O hydrogen bond, which forms an R 2 (2)(8) motif, and a C-H?O inter-action, which generates a C(8) chain along [010]. In addition, this chain structure is stabilized by C-H?? inter-actions. In one of the pyrrolidine rings, the methyl-ene group forming the flap of an envelope and the H atoms of the adjacent methyl-ene groups are disordered over two sets of sites, with site-occupancy factors of 0.571?(4) and 0.429?(4).

{1'-Phenyl-1',2',5',6',7',7a'-hexa-hydro-spiro-[indeno-[1,2-b]quinoxaline-11,3'-pyrrolizin]-2'-yl}(p-tol-yl)methanone.

Project description:In the title compound, C(35)H(29)N(3)O, the quinoxaline and indene systems are essentially planar, with maximum deviations of 0.047 (2) and 0.032 (2) Å for C atoms, respectively. The quinoxaline system forms a dihedral angle of 4.75 (3)° with the indene system. The pyrrolizine system is folded. The substituted five-membered ring adopts an envelope conformation. In the other five-membered ring, one C atom is disordered with a site-occupancy ratio of 0.676 (12):0.324 (12). In the crystal, mol-ecules are linked via C-H⋯O hydrogen bonds involving the bifurcated carbonyl O atom.

Crystal structures of 2'-benzoyl-1'-(4-methyl-phenyl)-1,1',2,2',5',6',7',7a'-octa-hydro-spiro-[indole-3,3'-pyrrolizin]-2-one and 2'-(4-bromo-benzoyl)-1'-(2-chloro-phen-yl)-1,1',2,2',5',6',7',7a'-octa-hydro-spiro-[indole-3,3'-pyrrolizin]-2-one.

Project description:The two title compounds, C28H26N2O2, (I), and C27H22BrClN2O2, (II), differ in their substituents, viz.4-methyl-phenyl and benzoyl rings in (I) replaced by 2-chloro-phenyl and 4- bromo-benzoyl, respectively, in (II). A significant difference between the two mol-ecules is found in the deviation of the benzoyl O atom from the least-squares plane of the ring to which it is attached [0.593?(4) and 0.131?(3)?Å, respectively], a fact which may be attributed to the different participation of the benzoyl O atoms as acceptors in their inter-molecular C-H?O inter-actions. The chemical modifications in (I) and (II) do not seem to affect the type nor strength of the inter-molecular N-H?N and C-H?O hydrogen bonds responsible for the two crystal structures, such that the aggregation of mol-ecules appears similar in spite of the mol-ecular changes.

Project description:In the title compound, C(29)H(26)N(2)O(2), one of the pyrrolidine rings in the pyrrolizine system is disordered, with site occupancies of ca 0.55 and 0.45. Both components of the disordered pyrrolidine ring adopt envelope conformations, whereas the other pyrrolidine ring adopts a twist conformation. The mol-ecules are linked into centrosymmetric dimers by N-H?O hydrogen bonds and the dimers are connected via C-H?? inter-actions.

1-Methyl-1'-(4-methyl-phen-yl)-2',3',5',6',7',7a'-hexa-hydro-1'H-dispiro-[piperidine-3,2'-pyrrolizine-3',3''-indoline]-4,2''-dione.

Project description:The title compound, C(26)H(29)N(3)O(2), crystallizes with two mol-ecules in the asymmetric unit, having C-H⋯O inter-actions between them and resulting in a dimer characterized by an R(2) (2)(11) motif. These dimers are linked into an ABABAB chain via N-H⋯O, N-H⋯N and C-H⋯O built edge-fused R(1) (2)(5) and R(2) (2)(7) motifs. This chain is linked to its inversion-related partner via N-H⋯O bonds with an R(2) (2)(8) motif and leads to a double chain extending along the b axis characterized by an R(6) (6)(36) motif across the inversion centres. The methyl group of the phenyl ring and the oxindole of mol-ecule A and B are involved in C-H⋯π inter-actions. One C atom of the pyrrolizine ring of mol-ecule A and its attached H atoms show positional disorder, the major and minor components being in the ratio 0.706 (7):0.294 (7).
